    Well the transition went well from my Biocube 32 to the 90 gallon.  So I pulled the trigger earlier than I thought and ordered five Discus. Order#13419


    I was trying to get some different colors and patterns to make it interesting. 


    Here's two pic's of the four in their new home.

    Wow even. Your fish are fantastic, they're not fully acclimated yet but they're already beautiful. You can actually see the difference in them in the bag. At first I would have thought why are you shipping twice as much as everyone else, but when I received the box and opened it. It was all worth it, professional and neat, and seeing the fish verified all that again. Except for the big fat one that arrived dead. All fish are fine now. I'm so glad I met you! I used to keep and breed a lot of discus, they are so fascinating!

    Hi- I felt I should let you know of my experience with the angels, cardinals and lilies. The angels and cardinals arrived, very well packaged. I appreciate the extra included cardinals, black out bags, superb packaging and included Nitrofurazone. After following the acclimation instructions the cardinals have done extremely well- active, great colors and eating well the day after acclimation. It has not been so smooth for the angels- they have not done well after acclimation, not eating, reclusive. I began the Nitrofurazone on day 2, but it hasn't helped. Unfortunately, 7 have perished, which makes me very sad. I do hope to order fish again, based on my experience with the cardinals.





    The lillies- superb!!!! Beautiful and very healthy!!!! I will definitely order these again soon. In the past, when I have ordered lillies elsewhere, I might get a bulb with one to two leaves. My purchase from you was very different- both were really spectacular, and impressive!! I just wanted to let you know of my thoughts. Best regards- Richard

    Yeah they were nice! The others are doing well and I get it sometimes they just don’t adjust from the stress of shipping. I am more bummed about losing all those cardinals and rummy nosed tetras to be honest.

    Michael, they all sparked up in a few hours. I did make a mistake and let the water in the bags into the tank. Its new water settled for a week, then one week with about 8 small fish, 2 crayfish and a snail. I am running 2 filters (75 Gal rating for each) on each side of my 65 Gallon aquarium and they have the bio filters that spin in front as the water exists the filter. I have a bag to absorb hardness in one filter. The water yesterday (before the intro of new fish) tested perfect in all the 5 test areas. PH is 7.0. Water temp 76 degrees. From Michael: Your water temperature is way too cold. Check my FAQs page for correct params.

    I decided to purchase from Discus.com after shopping around online, comparing prices, and reading reviews from a handful of different places. Ultimately, Discus.com was the cheapest (price per fish after shipping), and appeared to have a high quality product.





    I ordered 40 cardinal tetras on Wednesday 4/12/23 around noon. We had cold temps and bad weather coming in the following week so I chose Friday 4/14/23 as my desired delivery date. It was a short turn around for an overnight order but Michael made it happen.





    There were 49 fish shipped to me, two had died in shipping. I released 47 fish into my tank on Friday afternoon and all but 3 looked pretty good.





    On Saturday, they accepted some small pellets, and picked at sunken ones on the ground as well. 3 of the fish still looked stressed from shipping. Saturday night, 5 fish passed away. Water parameters were 0 Ammonia, 0 Nitrite, 20 ppm Nitrate. Air pump was on.





    On Sunday morning I still had 42 fish (2 more than I ordered), and I had some baby brine shrimp ready. All the fish ate well and really finished coloring up. 





    Today, Monday, four days later, all the fish appear to be doing well, eating well, and have colored up nicely.





    I'm very happy with the size, color, and health of the fish I received. I'm also very thankful for the great prices and and customer service from Michael at Discus.com.





    Michael has kept in touch with me after the sale as the fish have become acclimated to their new home. Thanks Michael and thanks Discus.com!

    Purchased a combination of cardinal, neon, and green neon tetra. They add a splash of color which looks amazing as they have started to school together. Of the two cardinals purchased I only received one where the red goes all the way back from the head and extends all the way down to the tail. Size was a little small for Fat AAA grade relative to the Jumbo neon tetra shown beside it in the attached image. From Michael: David, the cardinals are seasonal. Since these are all wild-caught, we are at the mercy of the fish lords depending on the season.

    The cardinal tetras are a great addition to my tank. Unfortunately I ordered 6 and all were dead except one and he is doing great. I will definitely order some more. From Michael: remind me next time, and I will make your loss whole. Unfortunately, due to the small size of these fish, they can be more fragile than other tankmates.

    Hi Michael,


     


    I received the package yesterday at 3:53 pm. Almost 4 hours later than their estimated 12pm delivery time. The fish bags were immediately temperature acclimated followed by a drip acclimation. Regarding the contents of the fish, I didn't received my order of the 4 Adolfo's Corydoras in the package and I didn't see any of the 5 large emperor Tetras. I did count 8 Gold Surinamese Tetra in that bag but I ordered only 6 so I guess I got two extras. The bag with the gold surinamese tetras was the bag with mass death as only two tetras in there were alive at the time. The bag with combined rummy and cardinal tetra had 3 deaths and the Bosmani Rainbow fish came in stressed with one laying upside down and subsequently died. The 3 Congo tetras were all females.

    They arrived yesterday and thank you for asking and I will send you a picture.  I’m a little concerned I lost one?  But my niece, who has much better eyes than myself, thinks it’s possibly a leaf caught in the filter.  But most are very deep blue; however, a couple’s bodies are somewhat translucent.  After this many tetras, additional substrate and plants - I think my tank will only be able to hold two discus (and I will have to pray to get lucky on getting a male and female).  My tank is a 46 gallon bow front with two hanging “Marineland Emperor 400 gallon” filters.  At one time I had three mature discus in it and they were a little crowded.  However, I did get fry several times, but the female always ate them once they were free swimming (heart breaking!). I am interested in two small discus (3 inches, thereabouts) and want some color and stripes, and a two small plecos - one with gold spots and one with white spots.  And I am open to any and all suggestions.  Thank you for checking on things and will send a picture directly.  Gregg

    Beautiful cardinal tetras! Doing great and eagerly eating! Would definitely order again.

Add a review

Cardinal Nose tetras are very good indicator fish in an aquarium. Their colors tend to fade in colour and intensity as water conditions deteriorate, a sure sign that a water change is needed. Cardinal nose tetras favor pristine water conditions.

Natural Habitat for Discus

Discus are found in floodplain lakes and flooded forests of the lowland Amazon River basin and some of its tributaries, including the Rio Negro.  These areas experience extreme changes in water level due to seasonal flooding.  Discus tend to congregate near fallen trees, known as “galhadas”, along the shore.  They prefer quiet water, and are rarely found in areas where there is strong current or wave action.

Discus Water Requirements

Discus prefer warm, soft, acidic water.  pH should be between 6.0 and 7.0, with hardness between 1° and 4° dKH (18 to 70 ppm).  Temperature should be kept between 82° and 89° F. Water conditions for both wild and hybrid discus are the same. While captive bred discus can be kept in dechlorinated tap water  reverse osmosis or deionized water supplemented will ensure the the best conditions. Discus require pristine water quality, and depending on the filtration system being used, a weekly or bi-weekly water change of 10% to 25% is highly recommended. Don’t forget to treat tap water with conditioner before refilling your aquarium!  

Housing Requirements for Discus

Discus grow to be quite large, and full sized discus will require an aquarium of 50 gallons or larger when they reach adult size.  Tall aquariums are best, to accommodate their body shape.  Current should be gentle, and décor if used at all should include large broadleaf plants and driftwood that is arranged vertically to simulate downed branches and trees.  A few floating plants can also be added to provide shaded areas and cover. Substrate should be fine to medium grade and smooth surfaced, as discus like to forage along the bottom for food.

Discus Behavior/Compatibility

Discus are generally calm, peaceful fish, but as cichlids they can be aggressive toward one another, especially when attempting to pair off and spawn.  Shy or submissive fish should be removed if they are unable to compete. Most serious hobbyists do not mix their discus with too many other species. However, suitable aquarium mates include cardinal tetras, neons, emperor and rummy nose tetras, as well as clown loaches and dwarf cichlids such as rams and Apistogramma species. All of these fish tolerate the high temperatures and low pH/hardness required by discus.  

What do Discus Eat?

In nature discus eat a considerable amount of plant material and detritus, but also forage along the bottom looking for worms and small crustaceans.  They are omnivores and will thrive on freeze dried black worms, beefheart, frozen blood worms, and a variety of pellet and flake food. Frozen and live foods may be fed as treats or to help induce spawning.  For best results, rotate their diet daily and feed only what they can consume in 2 to 3 minutes, once or twice a day.

Discus Breeding Level – Difficult

Captive bred discus will pair up and spawn relatively easily, but young, inexperienced parents may eat their eggs the first few times, particularly if other fish are present.  After hatching the young feed on heavy body mucus secreted by the parents for a few days until they begin to free-swim.  Parents will transfer the young back and forth several times a day.
